Taran Killam says goodbye to 'SNL' with hilarious 'Hard Knocks' spoof

Like a true sketch comedian, longtime Saturday Night Live cast member Taran Killam is marking his departure from the show with a farewell parody video.

Killam formally announced back in August that he won't be returning for his seventh season, but he saved a special personal goodbye for this week: a parody of HBO's Hard Knocks he posted to Twitter Wednesday. It's called “Live Knocks: Saying Goodbye to SNL.”

Liev Schreiber, who narrates the actual HBO documentary series, even leant his services to the parody, which also pokes fun at Killam's new movie, Brother Nature.

During Saturday Night Live 's 40th anniversary special , a whole musical number was devoted to actors breaking character. While breaking is considered unprofessional in some circles, SNL 's cast members have turned it into supplemental viewing, some a few too many times. (looking at you, Fallon .)
